I want to get a HELOC for my rental home that is $30K

[Michael Smith]

I own one sfh rental and it has appreciated in value. I am buying a second sfh outright in cash. I will own them both free and clear and they are each about $30k. I wanted to know whether you would recommend to get a HELOC to take my money back out of the house to purchase another similarly priced home or use the money for a downpayment on a duplex or triplex. How do banks feel about loaning on homes that are $30k. What percentage of the home value can I pull out. Thanks!
